Per Folder/File Themes
It is possible to customise the theme on a per folder or per file basis.
To do this simply add a *.fv file in the directory that you wish to create an alternative theme for. The name of this file must be the same as the theme name you are using for your site. For example, this site uses the "pelt" theme and the directory containing this file contains a pelt.fv file that customises the theme for this file (and any others that may be in this folder). In order to show this working we have simply stripped the PDF link from the theme.
For demonstration purposes we also provide a subfolder within this folder that has another modified theme.
